ELLIS S. ARCHER, OF PHILADELPHIA, PENNSYLVANIA.

LARD-LAMP.

`Specification of Letters Patent No. 2,671, dated June 18, 1842.

To all whom. it may concern.'

Be it known that I, ELLIS S. ARCHER, of the city and county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulImprovement in Lamps for Adapting Them to Burn Lard and other ConcreteSubstances, which is described as follows, reference being had to theannexed drawings of the same making part of this specification, ofwhich#m Figure l is a perspective view of the lamp. Fig. 2 is a verticalsection of the same.

The main body of the lamp is made in the usual manner. y

The improvement consists in combining with the lamp an `inverted tube Bopen at one end and closed at the other for melting the lard, Wax,spermaceti, or other concrete substances put into the receiver insteadof the oil for producing the light, the closed end of said tube beingformed into a hollow button A which serves the double purpose ofinipinging the air against the flame and as a conductor of heat, beingcomposed of copper or other suitable material for that purpose, the openor lower end being turned horizontally and passed through t-he innertube` into the receiver C, the aforesaid tube B being kept iilled Withthe lard or other combustible substance for the purpose of eX- cludingthe air therefrom and serving as a conductor of heat for melting themain body of the lard &c., in the receiver instead of having a column ofair in the tube as in Carrs lamp for burning lard.

The hollow button or ball A may be made of any required size and shape.The tube B connected with the button or ball should reach nearly to thebottom of the chamber or receiver C of the lamp Where it is inserted andmade fast and should be sutliciently eX- tended for the purpose ofkeepingthe lard wc. in a liquid and heated state for producing abrilliant light. The tubes are made of various shapes and sizes and suitany kind of lamps and may be used with or Without balls orbuttons on thetop or upper end, but

they must be closed at the top. One, two, or more tubes may be appliedto a lamp and may be heated at the side, center or other place or overthe flame so as to be used on any of the common lamps. The tube B andbutton or ball A may be first filled in order to exclude the airprevious to being soldered into the body o-f the lamp.

I do not claim to be the original inventor of a tube placed in thecenter of the lamp as this has heretofore been done; but

That I do claim as my invention and which I desire to secure by LettersPatent The combination of the hollow button A connected with the tube Bto be filled With lard and these with the `common Argand lamp C in themanner and Yfor the purpose set forth.
